WARNING!
In case the operator's manual is unclear or illegible all necessary information
can be obtained from manufacturer or the dealer.
2. INTRODUCTION
 This operator’s manual should be considered as the basic mower’s equipment and keep for
future use. If the mower is handed over to another operator, it should be in working condition
and given away along with operator’s manual and it’s other basic equipment.
 Operator’s manual is attached to every machine in order that the operator can familiarize
himself with design, working principles, service and adjustment of the mower. The user of
the mower should be familiar with common safety rules and procedures.
 The mower is manufactured according to international safety rules.
 Compliance with the warnings in this operator’s manual will ensure safe operation.
 Please contact your dealer if you have any queries relating to the operation and service of
the mower.
 This operator’s manual is an indispensable part of any machine and is intended to familiarize
future user with principles of proper operation and use of the machine as well as the risks
involved.
GENERAL WARNING

3. PROPER USE
Double-end disc mower is equipped with Perfect Cut cutterbar. In table 1 the mowing height
differences, depending on the tilt angle of the cutterbar are shown.

„Perfect Cut” cutting bar
No tilt

5° tilt
Standard mowing height
Optional heights when using high mowing toppingp
Optional heights when using high mowing double topping
Note: Grass, which is very rare should be mowed with zero angle inclination.
 The rear mounted disc mower is intended to mow green fodder: grass, alfalfa and such on
permanent grassland (pastures), on crop fields without rocks, and to form loose rows of cut
fodder. The pasture or field being mown should be even, best if prepared by rolling. In
the event of a majority of tall grass the first and second mowing should be done at a height of
6 - 7 cm (2.4" - 2.8"), while with a majority of short grasses at a height of 5 cm (2"). The last
mowing should be done a little higher - at 7 - 8 cm (2.8" - 3.1" ) from the ground.
 The rear mounted disc mower with crop scarifier/rollers is intended to mow green fodder:
grass, alfalfa and such on permanent grassland (pastures), on crop fields without rocks, and to
form loose rows of cut fodder. As a result of the passing of the layers of the green fodder
through the flails or rollers the grass stems are broken and a layer of wax is removed. This
facilitates and speeds up the drying process of the fodder by approximately 30 to 40%. The use
of rollers is especially recommended when mowing legumes such as alfalfa. Rollers are
particularly recommended for mowing grass legume such as alfalfa. The pasture or field being
mown should be even, best if prepared by rolling. This is especially true of mowers with rollers
as they tolerate rocks with a diameter of a few centimetres. If a larger stone is picked up stop
and remove it as it could cause damage of the discs. With a majority of tall grasses the first and
second mowing should be done at a height of 6 - 7 cm (2.4" - 2.8"), while with a majority of
short grasses at a height of 5 cm (2"). The last mowing should be done a little higher - at 7 - 8
cm (2.8" - 3.1") from the ground.
